nu'r Application filed September .7'0 old 2/) lmm it may concern:

rollton, in the county of Carroll andState of Kentucky, have invented certain new and 3 useful Improvements in Nut Locks, of which the following is a specification, reference being had therein to the accompanying drawings. p m

This inventifonrelates to pipe fitting locks and has for an object to provide a device for use especially with pipes to look a fitting which is interposed between two sections of pipe or equivalent members to prevent the coupling from becoming loosened from said pipe sections or either of them. i

A further object of the invention is to provide a look more especially, though not ex- .clus vely, intended for locking a union whereby two sections of pipes are coupled.

A further object of the invention is to i provide a lock which clamps over the pipes at both sides of and spans the coupling whereby both sections of the pipe and the coupling are locked into an organized structure. i

A. further ObJQCt of the inventlon s to provide a device especially adapted for use in connecting the exhaust line with the exhaust manifold of an automotive vehicle and'to lock the coupling so that said coupling is not loosened by thevibratlon of the operation of haust line with the union thereon coupled by meansofthe present invention, shown in side elevation; Figure 2 is a top plan view of the same fragment of the manlfold exhaust line union and lock; 1 Y

Figure 3 is a transverse sectional View through the exhaust line and lock'taken on line 3-3 of Figure 2; t

Figure 4 is a transverse sectional view a a through the exhaust manifold and lock, taken on line 47-4 of Figure 2;

Be it known that I, Woonronn Aglilirim, a citizen of the United States, residing at Caronfaiaonnron, KENTUCKY.

Loon. p re, 1921. Serial No. teaser.

Figure 5 is a perspective viewof the lock shownin open position, ready to be clamped upon the line and manifold, and,

Figure 6 1s a detail fragmentary view showing the relation of the latch and linln indicated conventionally at 10, is connected.

with the exhaust line 11 by means of a union The union is usually of the threaded type engaging the threads 18 upon the main ifoldstructure and by reason of the vibra{ tion of the machine and other parts becomes loosened and displaced. y

To prevent the loosening of the union, the present invention is provided comprising a band 14. preferably made continuous with a spring loop 15, whereby the band is proportioned to be clamped about the exhaust line 11. This clamping is provided by means of a link 16 pivoted in an eye 17 of the band with alatch member 18 proportioned to be inserted through the loop, as shown at Figure 5, and. pivoted to the end of the band 1 4 opposite the link 16 by means of a sleeve 19 the latch being pivoted in such sleeve by means of a pintle 20 which may or may not be integral with the latch as occasion or manufacture may make desirable. The sleeve 19 is upturned from the band by a bend 21 so that after the latch has been rotated substantially 90from the position shown at Figure 5 to the position shown at Figure 3, the link 16 is moved downwardly to latch over the sleeve 19 and to bear against the shoulders 22 formed integral or rigid with the latch 18, as shown at Figure 6.

v The band 1 is also provided with arms 23 so proportioned that when the band 14- is clamped uponthe linel], the arms 23 will clamp the sides of the union 12, as

shown in the drawing. The arms 23 are continued to form segments 24:, which, extending beyond the union 12, clamp the manifold 10 and by reason of its non-circular shape, as shown more particularly at Figure 4, prevent the rotation. of the structure relative to the manifold, even though the line itself might rotate. with or separately from the union 12. In other Words the clamp, clamping as it does upon the line 11 and upon the manifold 10 embracing the union 12, clamps rigidly and firmly upon all three of said units.

To release the device from clamping position, the latch 18 is rotated from the position shown at Figure 3 to the position shown at Figure 5, whereupon by reason of the shoulders 22 being positioned under the link 16, as shown more particularly at Figure 6, the link will be lifted over the sleeve 19 and released, permitting the resiliency of the bandto spread to the position shown-at Figure 5, whereupon it may be removed from'the line and union, or while in that position be replaced.

' What I claim is:

1. A nut lock comprising a band having means for clamping about a cylindrical member, arms extending from the band proportioned to clamp a nut, and extensions carried upon the arms proportioned to clamp an engaging member upon the side of the nut opposite the cylindrical member.

2. A coupling lock comprising a band proportioned to be clamped about a pipe,

arms carried by the band extending approximately in parallelism proportioned to clamp upon opposite sides of a coupling, and

extensions formed upon the arms proporarms having concave members proportioned A to clamp the conduit upon the side ot the union opposite the pipe.

4:. A union clamp comprising in combination with juxtaposed conduits and a union coupling, members extending along and:

upon opposite sides of the union and connected with members clamping the conduit upon opposite sides of said union.

In testimony whereof I hereunto allix my signature in presence of two witnesses.
